Moses-Euler Points: X(14030)-X(14047)
On July 21, 2017, Peter Moses noted a relatively simple form for a point P(k) on the Euler line: P(k) = b4 - b2c2 + c4 + k*(a4 + b2c2) : : (barycentrics)
The point is here named the Moses-Euler Point (k = f), where f is a function of (a,b,c), homogeneous of degree 0. The point is given by the combo P(k) = 3(k + 1)(a4 + b4 + c4)*X(2) + 4(k - 1)S2*X(4).
Following is a list of examples:
P(-8) = X(14030)
P(-7) = X(14031)
P(-6) = X(14032)
P(-5) = X(14033)
P(-4) = X(14034)
P(-3) = X(14035)
P(-2) = X(11361)
P(-1) = X(4)
P(0) = X(5025)
P(1) = X(2)
P(2) = X(7892)
P(3) = X(14001)
P(4) = X(14036)
P(5) = X(14037)
P(6) = X(14038)
P(7) = X(14039)
P(8) = X(14040)
P(infinity) = X(384)
P(-1/2) = X(14041)
P(1/2) = X(7901)
P(-3/2) = X(14042)
P(3/2) = X(14043)
P(-3/4) = X(14044)
P(-1/4) = X(14045)
P(1/4) = X(14046)
P(3/4) = X(14047)

P(4/3) =X(14067)
P(-5/3) = X(14068)
P(5/3) = X(14069)
Every point on the Euler line is a Moses-Euler (k = f(a,b,c)) point. A few more examples follow:
If k = (4S^2-(a^4+b^4+c^4))/(4S^2+(a^4+b^4+c^4)), then P(k) = X(3).
If k = (4S^2+(a^4+b^4+c^4))/(4S^2-(a^4+b^4+c^4)), then P(k) = X(5).
If k = (2S^2-(a^4+b^4+c^4))/(2S^2+(a^4+b^4+c^4)), then P(k) = X(20).
If k = (12S^2-(a^4+b^4+c^4))/(12S^2+(a^4+b^4+c^4)), then P(k) = X(140).
If k = ((a+b+c) (a^3-a^2 b-a b^2+b^3-a^2 c-b^2 c-a c^2-b c^2+c^3)+(a^4+b^4+c^4))/((a+b+c) (a^3-a^2 b-a b^2+b^3-a^2 c-b^2 c-a c^2-b c^2+c^3)-(a^4+b^4+c^4)), then P(k) = X(21).
If k = (a^6-a^4 b^2-a^2 b^4+b^6-a^4 c^2-2 a^2 b^2 c^2-b^4 c^2-a^2 c^4-b^2 c^4+c^6+(a^2+b^2+c^2) (a^4+b^4+c^4))/(a^6-a^4 b^2-a^2 b^4+b^6-a^4 c^2-2 a^2 b^2 c^2-b^4 c^2-a^2 c^4-b^2 c^4+c^6-(a^2+b^2+c^2) (a^4+b^4+c^4)), then P(k) = X(22).
The Shinagawa coefficients (G(a,b,c), H(a,b,c)) for the Moses-Euler point P(k) = b4 - b2c2 + c4 + k*(a4 + b2c2) : : are given by
G(a,b,c) = (k + 1)( - 1 + cot2 ω)
H(a,b,c) = 2(k - 1).
Shinagawa coefficients are defined in the Introduction, in Part 1 of ETC. Related tables, also accessible at the top and bottom of each Part of ETC, are the following:
S-Coefficients (Euler Line, ++)
S-Coefficients (Euler Line, +-)
S-Coefficients, Midpoints on Euler Line, I

Midpoints Not on Euler Line
Following are combos for the Moses-Euler point P(k):
P(k) = 3 (a^4 + b^4 + c^4) (1 + k) X(2) + 4 (k - 1) S^2 X(4)
P(k) = 3 (1 + k) (Cot(w)^2 - 1) X(2) + 2 (k - 1) X(4)

Let A'B'C' be the orthic triangle, and for arbitrary point P, let La be the line through A' parallel to AP, and define Lb and Lc cyclically. The locus of P such that La, Lb, Lc concur is the Jerabek hyperbola. The locus of the point of concurrence is the Feuerbach hyperbola of the orthic triangle, given by the barycentric equation
(SB - SC)(S2Ax2 + SBSCyz) + (SC - SA)(S2By2 + SCSAzx) + (SA - SB)(S2Cz2 + SASBxy) = 0.
The center of the hyperbola is X(1112), and the perspector is X(14052. The hyperbola passes through X(i) for these i: 4, 6, 52, 113, 155, 185, 193, 1162, 1163, 1829, 1839, 1843, 1858, 1986, 2574, 2575, 2904, 2905, 2906, 2907, 2914, 3574, 5095, 5895, 6152, 10294, 11817, 13202, 13420, 13431, as well and A' B' C' and the vertices of the cevian triangle of X(648).
See Antreas Hatzipolakis and César Lozada, Hyacinthos 26413.
Peter Moses (August 14, 2017) noted that this hyperbola appears in Example 2, page 145, in Clark Kimberling, "Conics associated with a cevian nest", Forum Geometricorum 1 (2001) 141-150.
The Hatzipolakis-Lozada hyperbola is the orthic isogonal conjugate of the Euler line, and the Feuerbach hyperbola of the orthic triangle if ABC is acute, and also the bicevian conic of X(4) and X(648). (Randy Hutson, November 2, 2017)

Le Viet An equilateral triangles: X(14169)-X(14188)
This preamble and centers X(14169)-X(14188) were contributed by César Eliud Lozada, August 30, 2017.
Let ABC be a triangle and BCA', CAB', ABC' equilateral triangles erected out/in - wardly of ABC. Let Bc, Cb be the circumcenters of CC'B and BB'C, respectively, and build Ca, Ac, Ab and Ba cyclically. Denote the circumcenters of BcCbA, CaAcB, AbBaC as Oa, Ob, Oc, respectively. Then, in each case, the triangle OaObOc is equilateral. (See: Hyacinthos 26551).
For BCA', CAB', ABC' built outwards ABC, the triangle OaObOc will be referred here as the outer-Le Viet An triangle.
This triangle has sidelength ObOc = 4*S^2*R*|(SW+sqrt(3)*S)/((sqrt (3)*SA+S)*(sqrt(3)*SB+S)*(sqrt (3)*SC+S))|.
Oa has coordinates: Oa = (SW+sqrt(3)*S)*a : (SB-SC)*b : (SC-SB)*c (trilinears)
For BCA', CAB', ABC' built inwards ABC, the triangle OaObOc will be referred here as the inner-Le Viet An triangle.
This triangle has sidelength ObOc = 4*S^2*R*|(SW-sqrt(3)*S)/((sqrt (3)*SA-S)*(sqrt(3)*SB-S)*(sqrt (3)*SC-S))|
Oa has coordinates: Oa = (SW-sqrt(3)*S)*a : (SB-SC)*b : (SC-SB)*c (trilinears)
Both triangles are perspective to the anti-orthocentroidal triangle.
The outer-Le Viet An triangle is orthologic to these triangles: 1st Ehrmann, inner-Le Viet An and inner-Napoleon. It is also parallelogic to these triangles: inner-Le Viet An and outer-Napoleon.
The inner-Le Viet An triangle is orthologic to these triangles: 1st Ehrmann, outer-Le Viet An, 1st Morley, 2nd Morley, 3rd Morley, outer-Napoleon, Roussel, Stammler. It is also parallelogic to these triangles: 1st Ehrmann, outer-Le Viet An, 1st Morley, 2nd Morley, 3rd Morley, outer-Napoleon, Roussel, Stammler.
When constructing the outer- and the inner- Le Viet An triangles, the Euler lines of BcCbA, CaAcB, AbBaC are concurrent at X(14185) and X(14187), respectively.

Nguyen Images: X(14206) - X(14213)
Let ABC be a triangle, let L be the line through B orthogonal to BC, let BA be any point on L, and let BC be the point such that BBABCC is a rectangle. Likewise, let CCBCAA be a rectangle with base CA and let AACABB be a rectangle with base AB. Let A' be the midpoint of BACA, and define B' and C' cyclically. Let LA be the line through A' perpendicular to BC, and define LB and LC cyclically. Nguyen Ngoc Giang found that the lines LA, LB, LC concur. (Received from Dao Thanh Oai, August 11, 2017)
If you have The Geometer's Sketchpad, you can view Nguyen Rectangles.
Peter Moses analyzed the construction (August, 2017) as follows. Let U be the ratio of the height of the rectangle BBABCC to the base; that is, U = |BAB|/a. Define V and W cyclically. The point X' of concurrence is given by
X' = (a2 + b2 - c2)(a2 - b2 + c2) - 2a2SU + (a2 + b2 - c2)SV + (a2 - b2 + c2)SW : : (barycentrics)
The triangles ABC and A'B'C' are orthologic, and X' is the A'B'C'-to-ABC orthologic center. The ABC-to-A'B'C' orthologic center, X'', is given by
X'' = 1/(-a2 + b2 + c2 + SU) : :
If X is a point in the plane of ABC, then it has actual trilinear distances (possibly nonpositive) that are the heights of rectangles as in the above construction. Therefore, starting with X = x : y : z (barycentrics), we have U = kx/a2, where k = S/(x + y + z), and V = ky/b2 and W = kz/c2. Consequently,
X' = 2a(abc)2 (cos B cos C)(x + y + z) + S2 (-abcx + a2 cy cos C + a2 bz cos B) : :
Equivalently,
X' = X' = (H - abcS2)x + (H + S2 a2 c cos C)y + (H + S2 a2 b cos B)z : : , where H = 2a(abc)2 (cos B cos C).
Also,
X' = a (c2 SC (3 S2 - 2 SC SA) y + b^2 SB (3 S2 - 2 SA SB) z - b2 c2 (S^2 - 2 SB SC) x) : :
The point X' is here named the Nguyen image of X, and the point X'', the adjoint Nguyen image of X, given by
X'' = (x + y + z)/(a2SA(x + y + z) + 4S2x)
The appearance of (i,j) in the following list means that the X(j) = Nguyen image of X(i): (3,14211), (6,92), (511,14206), (512,14207), (513,4468), (518,908), (520,14208), (523,661), (524,1959), (525,14209), (1350,14212), (1351,14213), (2574,2582), (2575,2583), (8675,1577), (8999,4391), (9000,693), (9001,514), (9002,4462), (9004,3912), (9026,4358), (9027,14210), (9051,6332), (11477,63).

Nguyen-Euler centers: X(14226)-X(14245)
This preamble and centers X(14226)-X(14245) were contributed by César Eliud Lozada, September 4, 2017.
This section is based on Nguyen Ngoc Giang's paper mentioned in the preamble just before X(14206). The paper appears in the International Journal of Computer Discovered Mathematics, vol 2(2017), pp 135-140.
Let BBACAC, CCBABA, AACBCB be three rectangles built on the sides of a triangle ABC, such that |BBA|/a = |CCB|/b = |AAC|/c = λ = constant. Assume that λ %gt; 0 means that rectangles are built outwards from ABC and λ < 0 means that rectangles are built inwards from ABC. Nguyen proved that if NA, NB, NC are X(5) (i.e., the nine-point-center) of triangles ABACA, BCBAB and CACBC, respectively, then triangles NANBNC and ABC are orthologic.
In addition, it can be proved that if the three nine-point-centers (the N's) are replaced by any other point P on the Euler line such that (X(3)P)|/(X(3)X(4)) = (OP)/(OH) = t, a constant invariant of (a,b,c), then the triangles PAPBPC and ABC remain orthologic. In this case, the orthologic center PAPBPC to ABC is:
X' = (2*a^6 - (b^2+c^2)*(a^4+(b^2-c^2)^2))*(3*t-1)*λ - 2*S*(a^2+b^2-c^2)*(a^2-b^2+c^2) : : (barycentrics)
and the orthologic center ABC to PAPBPC:
X" = 1/(((2*a^4 + 2*(b^2+c^2)*a^2 + 4*b^2*c^2 - 4*(b^2+c^2)^2)*t + (a^2+b^2+c^2)*(-a^2+b^2+c^2))*λ + 2*S*(-a^2+b^2+c^2)) : : (barycentrics)
The point X' is here named the Nguyen-Euler(λ) point of P, and the point X", the Nguyen-Euler(λ) adjoint point of P.
For every λ and P,:
X' lies on the van Aubel line X(4)X(6), and |X(4)X'|/|X(4)X(6)| = λ*(3*t - 1)*cot(ω), where ω is the Brocard angle of ABC; moreover, X" lies on the Kiepert hyperbola.

"Let F1, F2, F3 be three figures in perspective two and two in the same plane, show that if they have a common centre of perspective, their three axes of perspective are concurrent." (Quoted from Lachlan, R.: An Elementary Treatise on Modern Pure Geometry, McMillan & Co., 1893, pp. 123).

X(14379) is the perspector of the circumconic concentric and homothetic to the following conic described by Paul Yiu in response to a problem posed by Randy Hutson (Hyacinthos #21973 and related, 4/17/2013):
Let A'B'C' be the pedal triangle of X(1498) (which is also the cevian triangle of X(20)). Let Ba, Ca be the orthogonal projections of A' onto lines CA, AB, resp. Define Cb, Ab, Ac, Bc cyclically. The points Ba, Ca, Cb, Ab, Ac, Bc lie on a conic, here named the Yiu-Hutson conic. Note: If X(4) is substituted for X(1498), the conic is the Taylor circle. The Yiu-Hutson conic has center X(14390) and is given (Paul Yiu, Hyacinthos #21973 4/17/2013) by this barycentric equation:
(4/S^2) cyclic sum ((a^4 SA^2)/(SA*SB + SA*SC -SB*SC}))yz - (x + y + z)^2 = 0
An alternative construction for points Ba, Ca, Cb, Ab, Ac, Bc above follows: Let A'B'C' be the half-altitude triangle. Then Ab = BC∩C'A', Ac = BC∩A'B', and Bc, Ba, Ca, Cb are defined cyclically. Note: The centroid of BaCaCbAbAcBc is X(2). (Randy Hutson, September 10, 2017)

Koutras-Hatzipolakis-Moses points: X(14459)-X(14478)
Following problem 1165a in Stathis Koutras's posting to Romantics of Geometry, Antreas Hatzipolakis posed the following in Hyacinthos 26601, September 12, 2017:
Let P be a point in the plane of a triangle ABC. Let
LAC = line through A parallel to line CP, and define LBA and LCB cyclically
A' = BC∩LAC, and define B' and C' cyclically
MA = midpoint of A and A', and define MB and MC cyclically.
A* = AMC∩B'C', and define B* and C* cyclically.
The points A*, B*, C* are collinear (Koutras).
LAB = line through A parallel to line BP, and define LBC and LCA cyclically
A'' = BC∩LAB, and define B'' and C'' cyclically
NA = midpoint of A and A'', and define NB and NC cyclically.
A** = ANB∩B''C'', and define B** and C** cyclically.
The points A**, B**, C** are collinear. (Hatzipolakis).
What can be said about the point of intersection of the lines A*B*C* and A**B**C**? (Hatzipolakis)
Peter Moses responds as follows. Write P = p : q : r (barycentrics). The point of intersection, here denoted by KHM(P), lies on the line PX(2) and is given by
KHM(P) = p3 - q3 - r3 + 3p2(q + r) - 2qr(q + r) - pqr : :
and by the following combo:
KHM(P) = 3 (p3 + q3 + r3 + 2 (q r (q + r)+ r p (r + p) + p q (p + q) + 3 p q r))*X(2) - (p + q + r) (2 (p2 + q2 + r2) + 5 (q r + r p + p q))*P
The appearance of (i,j) in the following list means that KHM(X(i)) = X(j): (1,14459), (3,14460), (4,14461), (5,14462), (6,14463), (8,5212), (10,14464).
The mapping P → KHM(P) is a two-to-one mapping in the sense that if
P' = 3 p^4-6 p^3 q+2 p^2 q^2+8 p q^3-4 q^4-6 p^3 r+14 p^2 q r-14 p q^2 r+q^3 r+2 p^2 r^2-14 p q r^2+9 q^2 r^2+8 p r^3+q r^3-4 r^4 : : ,
then KHM(P') = KHM(P). An example of a pair (P,P') is (X(1),X(14478)). (Peter Moses, September 13, 2017).
The locus of a point P such that KHM(P) = P is the cubic, here named the KHM cubic, given by the following barycentric equation:
x3 + y3 + z3 + 2y2z + 2yz2 + 2x2z + 2xz2 + 2x2y + 2xy2 + 6xyz = 0.
If 1 ≤ i ≤ 15000, then X(i) does not lie on the KHM cubic. If P is a point then the line GP meets the KHM cubic in this point:
(2 p - q - r) ((p + q + r)^2 - 3 (q r + r p + p q) - 3 (q - r)^2 - (7 (27 p q r + 2 (p + q + r)^3 - 9 (p + q + r) ((q r + r p + p q)))^2)^(1/3)) : :

Nguyen-Moses images: X(14483)-X(14498)
Let ABC be a triangle, let L be the line through B orthogonal to BC, let BA be any point on L, and let BC be the point such that BBABCC is a rectangle. Likewise, let CCBCAA be a rectangle with base CA and let AACABB be a rectangle with base AB. Let LA be the line through A perpendicular to BCCB, and define LB and LC cyclically. Starting with Nguyen Ngoc Giang's rectangles (as in the preamble just before X(14206)), Peter Moses (September 19, 2017) found that the lines LA, LB, LC concur.
Let U be the ratio of the height of the rectangle BBABCC to the base; that is, U = |BAB|/a. Define V and W cyclically. The point X' of concurrence is given by
X' = 1 / (-a^2 + b^2 + c^2 + 2 S U) : : (barycentrics)
If X is a point in the plane of ABC, then it has actual trilinear distances (possibly nonpositive) that are the heights of rectangles as in the above construction. Therefore, starting with X = x : y : z (barycentrics), we have U = kx/a2, where k = S/(x + y + z), and V = ky/b2 and W = kz/c2. Consequently,
X' = a^2 / (a^2 (-a^2 + b^2 + c^2) + 2 S^2 x (x + y + z)) : :
The point X' is here named the Nguyen-Moses image of X.
The appearance of (i,j) in the following list means that the X(j) = Nguyen-Moses image of X(i):

Let A'B'C' be the 1st Schiffler triangle of ABC. Let Aa', Bb', Cc' be the orthogonal projections of A, B, C on B'C', C'A', A'B', respectively, and A'a, B'b, C'c the orthogonal projections of A', B', C' on BC, CA, AB. These six points lie on a circle here named the 1st Schiffler circle, with center X(14526) and squared radius ((9*R+2*r)*R^2*r^2+(R+2*r)*S^2)*R/((R+2*r)^2*(3*R+2*r)^2). This circle passes through X(11) and X(1365) and is the circumcircle of the pedal triangles of the isogonal conjugate pair X(35) and X(79).
Next, if "1st Schiffler triangle" is replaced by "2nd Schiffler triangle", the resulting six points lie on a circle, here named the 2nd Schiffler circle, with center X(1737) and squared radius R*r^2/(R-2*r). This circle passes through X(11), X(5532), X(13141), X(14027) and is the circumcircle of the pedal triangles of the isogonal conjugate pair X(36) and X(80).
Continuing, let A'B'C' be the 1st Schiffler triangle and A"B"C" the 2nd Schiffler triangle of ABC. Let A1, B1, C1 be the orthogonal projections of A', B', C' on B"C", C"A", A"B", respectively, and A2, B2, C2 the orthogonal projections of A", B", C" on B'C', C'A' and A'B'. These six points A1, B1, C1 , A2, B2, C2 lie on a circle here named the 3rd Schiffler circle, with center X(14527). This circle also passes through X(11).

Nguyen orthoimages: X(14538)-X(14541)
Let ABC be a triangle, let L be the line through B orthogonal to BC, let BA be any point on L, and let BC be the point such that BBABCC is a rectangle. Likewise, let CCBCAA be a rectangle with base CA and let AACABB be a rectangle with base AB. Let A' = ABCB∩ACBC, and define B' and C' cyclically. Let LA be the line through A' orthogonal to line BC, and define LB and LC cyclically. Nguyen Ngoc Giang found that the lines LA, LB, LC concur. See the preamble just before A(14206).
If you have The Geometer's Sketchpad, you can view Nguyen Triangle.
Let U be the ratio of the height of the rectangle BBABCC to the base; that is, U = |BAB|/a. Define V and W cyclically. Peter Moses found (September 23, 2017) that the point X' of concurrence of the lines LA, LB, LC is given by
X' = 2a2(a2 - b2 - c2)UV + 2a2(a2 - b2 - c2)UW + (a2 + b2 - c2)(a2 - b2 + c2)VW : :
If X is a point in the plane of ABC, then it has actual trilinear distances (possibly nonpositive) that are the heights of rectangles as in the above construction. Therefore, starting with X = x : y : z (barycentrics), we have U = kx/a2, where k = S/(x + y + z), and V = ky/b2 and W = kz/c2. Consequently,
X' = 2a2c2(a2 - b2 - c2)xy + 2a2b2(a2 - b2 - c2)xz + a2(a2 + b2 - c2)(a2 - b2 + c2)yz : :
X' = a2(SBSCyz - b2SAxz - c2SAxy : :
X' = isogonal conjugate of the X(3)-vertex conjugate of X
X' = reflection-in-X(3) of the isogonal conjugate of P
The triangle A'B'C' is here named the X-Nguyen triangle, and the point X' is named the Nguyen orthoimage of X.

The mapping X → X' takes the circumcircle to the infinity line, and the infinity line to the circumcircle, in cycles. In the following list, i → j means that X(i) → X(j):
30 → 110 → 523 → 74 → 30
100 → 513 → 104 → 517 → 100
101 → 514 → 103 → 516 → 101
102 → 515 → 109 → 512 → 102
105 → 518 → 1292 → 3309 → 105
106 → 519 → 12193 → 3667 → 106
107 → 520 → 1294 → 6000 → 107
108 → 521 → 1295 → 6001 → 108
Chains of Nguyen orthoimages can be read from the list. These include the following:
3426 → 2 → 1350
3424 → 6 → 376 → 11820
3637 → 2131 → 3348 → 3346 → 64 → 4 → 3 → 20 → 1498 → 3183 → 2130 → 3355
3473 → 3354 → 3347 → 3345 → 84 → 1 → 40 → 1490 → 3182 → 3353 → 3472
All the points on those last two chains lie on the Darboux cubic, K004. p
The inverse of the mapping P → P', where P = p : q : r, is given bya^2 (2 a^2 b^2 p-2 b^4 p+2 b^2 c^2 p+a^4 q-b^4 q-2 a^2 c^2 q+c^4 q+2 a^2 b^2 r-2 b^4 r+2 b^2 c^2 r) (2 a^2 c^2 p+2 b^2 c^2 p-2 c^4 p+2 a^2 c^2 q+2 b^2 c^2 q-2 c^4 q+a^4 r-2 a^2 b^2 r+b^4 r-c^4 r) : : ,
this being the isogonal conjugate of the reflection-in-X(3) of P. (Peter Moses, September 25, 2017)
The X-Nguyen triangle A'B'C' is perspective to ABC if X is on one of the following: (1) the line at infinity; (2), the circumcircle; (3) a quartic curve that passes through X(i) for i = 3, 4, 64, 2574, 2575; and (4) the circle with center X(3) and radius R*sqrt(5), here named the Nguyen-Moses circle. If X is on the circumcircle, then the points given by combos 4*X(3) - (5 + sqrt(5))*X and 4*X(3) - (5 - sqrt(5))*X is on the Nguyen-Moses circle. (Peter Moses, September 25, 2017)

Singular Foci of Cubics: X(14649)-X(14706)
Let O(P) denote the orthopivotal cubic of a point P, as defined at Orthopivotal cubics. Five points on this cubic are A, B, C, X(13), and X(14). The singular focus of O(P), denoted by Psi(P) defines an involutory mapping P → Psi(P), and Psi(P) is called the Psi-transform of P. The centers X(14649)-X(14706) involve these orthopivotal cubics for these points: X(14651), X(14656), X(14660), X(14704), X(14705), X(14706). The others involve circular cubics.

Involution and related centers: X(14782)-X(14806)
This preamble and centers X(14782)-X(14806) were contributed by César Eliud Lozada, October 10, 2017.
"When several pairs of points A, A'; B, B' ; C, C′ ; . . . lying on a straight line are such that their distances from a fixed point O are connected by the relations
OA .OA' = OB.OB' = OC.OC′ = . . . ,
the points are called a range in involution." (Lachlan, R.: An Elementary Treatise on Modern Pure Geometry. MacMillan & Co., 1893, chapter 5, pp. 37-41).
A range in involution is denoted by {A, A′}, {B, B′}, {C, C′}. The point O, collinear with the given points, is called the center of involution and each pair of corresponding points, as A and A′, are said to be a conjugate-couple.
To construct O, let {A, A'}, {B, B'} be two pairs of points on a straight line. Through A and B draw any two lines AP, BP intersecting in P and through A', B' draw A'Q, B'Q parallel to BP, AP respectively, meeting in Q. PQ meets AB in O. (Proof in the above reference). From this construction, it is clear that two pairs of points are sufficient for determining the range unambigously and its notation can be shortened to {A, A'}, {B, B'}.
Some properties:
1) Suppose A, A′, B, B′ are four distinct collinear points. Let ΓA be any circle through A and A′ and ΓB any circle through B and B′. Then, for all ΓA and ΓB, their radical axis passes through O, the center of involution of {A, A′}, {B, B′}.
2) If all the points in a range in involution lie on the same side of the center of involution, there exist two real points, one on either side of the center, each of which coincides with its own conjugate. These points are called the double points of the involution. (Construction: from the center of involution O draw the tangent OT to any circle through a pair of conjugate points, for example A, A′. The circle (O,T) cuts AA′ in S and S′ which are the double points of the involution).
3) Any pair of conjugate points of a range in involution are harmonic conjugates with respect to the double points of the involution.
Trilinear coordinates:
Supose Y = Uy : Vy : Wy and Z = Uz : Vz : Wz (trilinears) and let′s assume that Y′, Z′ are such that YY' = λ YZ and ZZ' = μ YZ. Let X be another point such that YX = ϰ YZ.
The center of involution of {Y, Y'}, {Z, Z'} has coordinates:
O = Uy (λ - 1) (a Uz + b Vz + c Wz) - Uz μ (a Uy + b Vy + c Wy) : :
= (λ - 1) Y - μ Z
If O = Uo : Vo : Wo then X', the conjugate-couple of X, has coordinates:
X' = μ ((a Uz + b Vz + c Wz) Uy - ((Uy Vz - Uz Vy) b + (Uy Wz - Uz Wy) c) λ) + ϰ Uo : :
The double points of the involution have coordinates:
S± = ± η ((Uy Vz - Uz Vy) b + (Uy Wz - Uz Wy) c) μ + Uz μ (a Uy + b Vy + c Wy) - Uy (λ - 1) (a Uz + b Vz + c Wz) : :
where η = sqrt((λ - μ) (λ - 1)/μ).
The following table contains the ETC indexes of points forming some ranges in involution, their centers and double points, when these are real.

Ghoicas-Lozada Images: X(14815)-X(14825)
This preamble was developed by Peter Moses and Clark Kimberling, October 11, 2017.
The following material is based on a construction by M. D. Ghoicas in 1934; see Antreas Hatzipolakis and César Lozada, Hyacinthos 26655. Let P be a point in the plane of a triangle ABC, not on one of the three sidelines, and let P* be the isogonal conjugate P*. Let
AB = AP∩BC, and define BC and CA cyclically.
AC = AP*∩BC, and define BA and CB cyclically.
A' = BBC /\ CCB, and define B' and C' cyclically.
A'' = BBA /\ CCA, and define B'' and C'' cyclically.
Then the following pairs of triangles are perspective: ABC and A'B'C', ABC and A''B''C'', and A'B'C' and A''B''C''. Let
Q = ABC and A'B'C'
Q* = perspector of ABC and A'B'C'
GL(P) = perspector of A'B'C' and A''B''C''
The point GL(P) is here named the Ghoicas-Lozada image of P. Let
U = angle BAP = angle CAP*, V = angle CBP = angle ACP*,
W = angle ACP = angle BAP*
Homogeneous trilinear coordinates for Q, Q*, and G(L,P) are as follows:
Q = (sin A)/sin(A - U) : (sin B)/sin(B - U) : (sin C)/sin(C - U) (cf. TCCT p.177, and much earlier: A. G. Burgess, "Concurrency of lines joining vertices of a triangle to opposite vewrtices of triangles on its side," Proceedings of the Edinburgh Mathematical Society 33 (1913-1914) 58-64; especialy p. 60.)
Q* = sin(A - U)/sin A : sin(B - U)/sin B : sin(C - U)/sin C
GL(P) = sin U sin(B - V) sin(C - W) + sin V sin W sin(A - U) : sin V sin(C - W) sin(A - U) + sin W sin U sin(B - U) : sin W sin(A - U) sin(B - V) + sin U sin V sin(C - V)
If X is a triangle center, then GL(X) is a triangle center.
If P= p : q : r (barycentrics), then GL(P) = a2p(c2q2 + b2r2) : :
If X = x : y : z (trilinears), then GL(X) = x(y2 + z2) : :
GL(P) = crosspoint of P and the isogonal conjugate of P
GL(P) = crosssum of P and the isogonal conjugate of P

Simpedal points: X(14870)-X(14889)
This preamble and centers X(14870)-X(14889) were contributed by César Eliud Lozada, October 19, 2017.
"To determine a point P whose pedal triangle A'B'C' with regard to a given triangle ABC shall be similar to a given triangle A*B*C*". (Johnson, Roger A.: Advanced Eucliden Geometry, Dover, New York, 1960, problem 205, pp. 142.)
Assume ABC and A*B*C* are not inversely similar. For finding P, take any two points B1, C1 on AC and AB, respectively, and build A1B1C1 directly similar to A*B*C*. Then, through A2=AA1∩BC, draw parallels to A1B1 and A1C1, cutting AC and AB at B2 and C2, respectively. The required P is the Miquel point of A2B2C2 with respect to ABC. (Proof in the cited reference).
The point P and the triangle A'B'C' will be named here the simpedal point of A*B*C* in ABC and the simpedal triangle of A*B*C* in ABC, respectively.
Let A* = UA : VA : WA (trilinears) and similarly B* and C*. Let M be the trilinear matrix of A*B*C* and mij the (i, j)-minor of M. Denote δij = (-1)i+j mij. Then,
P = a (b δ33 δ21 (a^2 - b^2) + c δ22 δ31 (a^2 - c^2) + b c (b δ32 δ21 + c δ23 δ31) - (δ21 δ31 + δ22 δ32 + δ23 δ33) a b c + a δ22 δ33 (b^2 + c^2 - a^2))/(a UA + b VA + c WA) : :
The appearance of (T, I, J) in the following list means that X(I) is the simpedal point of triangle T in ABC and X(J) is the simpedal point of ABC in triangle T:

Brocard-Lemoine points: X(14941)-X(14952)
This preamble and centers X(14941)-X(14952) were contributed by César Eliud Lozada, October 24-27, 2017.
Let ABC be a triangle, P any point in its plane (not on its sidelines) and A', B', C' the traces of P on ABC. Let Ab, Ac be the points where BC is cut by the parallel to AB through B' and the parallel to AC through C', respectively. Build Bc, Ba, Ca, Cb cyclically. Then lines AAb, BBc, CCa concur at a point W1 and lines AAc, BBa, CCb concur at a point W2.
For P = u : v : w (trilinears), W1 and W2 have trilinears as shown:
W1 = c/v : a/w : b/u
W2 = b/w : c/u : a/v
Note that for P=X(6), W1 and W2 are the Brocard points of ABC.
The previous construction is due to Lemoine as an attempt to generalize the Brocard geometry (Roger A. Johnson, Advanced Eucliden Geometry, Dover, New York, 1960, §499-500, pp. 299). Johnson writes, these points have many properties resembling those of the Brocard points.
Some properties:
a) For P=X(2), W1=W2=X(2)
b) Points Ab, Ac, Bc, Ba, Ca, Cb lie on a conic (here named the Brocard-Lemoine conic of P) with center O(P) given by:
O(P) = (a^4*u^4-a*u*(b*v+c*w)*(3*b*c*v*w+a^2*u^2)-(b^2*v^2+c^2*w^2)*(b*c*v*w+3*a^2*u^2)-b*v*c*w*(-b*c*v*w+2*a^2*u^2))/a : : (trilinears)
O(P) = x^4-x*(y+z)*(x^2+3*y*z)-(y^2+z^2)*(3*x^2+y*z)-y*z*(2*x^2-y*z) : : (barycentrics)
- For P=X(194), the conic is a circle centered at X(14135) and having squared-radius = ∏(3*S^2-4*SB*SC-SW^2)/(64*R^2*S^4)
c) The trilinear pole Q(P) of the line W1W2 has coordinates:
Q(P) = u*(b^2*v^2-a*c*u*w)*(c^2*w^2-a*b*u*v) : : (trilinears)
Q(P) = x*(y^2-x*z)*(z^2-x*y) : : (barycentrics for P=x:y:z)
- For P on the line at infinity, Q(P) = P
- For P on the Steiner circumellipse, Q(P) = X(2)
- For any other P, Q(Q(P)) = P, i.e., pairs {P, Q(P)} form a conjugation.
Following the last property, Q(P) will be named here the antitomic conjugate of P. This conjugacy was mentioned by Randy Hutson in X(9513), although its explanation was left pending. In a personal communication (Oct 26, 2017), Hutson gives the reasons for this name:
As the antigonal conjugate of a point P is defined as:
1) The isogonal conjugate of the inverse in the circumcircle (=isogonal conjugate of the line-at-infinity) of the isogonal conjugate of P,
I define the antitomic conjugate of P as:
1) The isotomic conjugate of the inverse in the Steiner-circumellipse (=isotomic conjugate of the line-at-infinity) of the isotomic conjugate of P.
Randy Hutson also notes that Q(P) is the antipode of P in the hyperbola {A,B,C,X(2),P}.
The appearance of {I,J} in the following list means that Q(X(I)) = X(J) (for P not at infinity and not on the Steiner circumellipse):

Bicentrically induced harmonic conjugates: X(14953)-X(14966)
This preamble and centers X(14953)-X(14966) were contributed by Clark Kimberling and Peter Moses, October 25, 2017.
Using barycentric coordinates, suppose that P = p : q : r and U = u : v : w are a bicentric pair of points. Let
P' = line p*x + q*y + r*z = 0
U' = line u*x + v*y + w*z = 0
L = a line
P* = L∩P'
U* = L∩U'
X = a point on L
X' = (P*,U*)-harmonic conjugate of X, to be expressed as L(P,U)-harmonic conjugate of X
If L is a central line and X is a triangle center, then X' is a triangle center. For example, if X is on the Euler line, then X' is on the Euler line, for every choice of bicentric pair (P,U), and the point X' in this case is written as Euler(P,U)-harmonic conjugate of X. If X is on the Brocard axis, then X' is written as Brocard(P,U)-harmonic conjugate of X.

Recall that P(1) and U(1) are the 1st and 2nd Brocard points, given in trilinears by P(1) = c/b : a/c : b/a and U(1) = b/c : c/a : a/b.

The term altimedial triangle was introduced in Hyacinthos 253, by Antreas Hatzipolakis, January 30, 2000. A recap follows:
Let MA, MB, MC be the midpoints of sides BC, CA, AB, resp.
Let HA, HB, HC be the feet of the altitudes from A, B, C, resp.
The triangles HAMCMB, MCHBMA, MBMAHC are the A-, B- and C-altimedial triangles. Each is inversely congruent to the medial triangle and inversely similar to ABC (with center of inverse similitude the respective vertex of the orthocentroidal triangle).
The A-altimedial triangle has barycentric vertex matrix:
0 : tan B : tan C
1 : 1 : 0
1 : 0 : 1
The A-, B- and C-anti-altimedial triangles, AABACA, ABBBCB, ACBCCC are here introduced as the triangles of which ABC is the A-, B- and C-altimedial triangle, resp. To construct the A-anti-altimedial triangle, take AA as the reflection of A in line BC. Then BA is the reflection of AA in B, and CA is the reflection of AA in C. The B- and C-anti-altimedial triangles are constructed cyclically. The anti-altimedial triangles are each inversely congruent to the anticomplementary triangle and homothetic to the respective altimedial triangle, with center of homothety the respective vertex of the orthocentroidal triangle.
The A-anti-altimedial triangle has barycentric vertex matrix:
-a2 : a2 + b2 - c2 : a2 - b2 + c2
a2 : a2 - b2 + c2 : -a2 + b2 - c2
a2 : -a2 - b2 + c2 : a2 + b2 - c2
The triangles AAABAC, BABBBC, CACBCC are here named the A-, B- and C-adjunct anti-altimedial triangles. Each are inversely similar to ABC, with center of inverse similitude X(3).
The A-adjunct anti-altimedial triangle has barycentric vertex matrix:
-a2 : a2 + b2 - c2 : a2 - b2 + c2
-a2 + b2 + c2 : b2 : a2 - b2 - c2
-a2 + b2 + c2 : a2 - b2 - c2 : c2
Let P be a triangle center. Let PA be P-of-A-altimedial-triangle, and define PB, PC cyclically. Triangle PAPBPC is here named the P-of-altimedial-triangles triangle, or P-altimedial triangle for short. For all finite P other than X(3) (for which the P-altimedial triangle is the triple point X(5)), the P-altimedial triangle is inversely similar to the medial triangle, with center of inverse similitude X(5).
The X(1)-altimedial triangle is also the orthic triangle of the Fuhrmann triangle.
The X(20)-altimedial triangle is also the X(4)-Brocard triangle.
Let P'A be P-of-A-anti-altimedial-triangle, and define P'B, P'C cyclically. Triangle P'AP'BP'C is here named the P-of-anti-altimedial-triangles triangle, or P-anti-altimedial triangle for short. For all finite P other than X(5) (for which the P-anti-altimedial triangle is the triple point X(3)), the P-anti-altimedial triangle is inversely similar to ABC, with center of inverse similitude X(3).
The X(3)-anti-altimedial triangle is also the X(3)-Fuhrmann triangle.
The X(10)-anti-altimedial triangle is also the inner Garcia triangle.
If P is a point on the Euler line, the P-altimedial and P-anti-altimedial triangles are both homothetic to the orthocentroidal and anti-orthocentroidal triangles.
Let P"A be P-of-A-adjunct-anti-altimedial-triangle, and define P"B, P"C cyclically. Triangle P"AP"BP"C is here named the P-of-adjunct-anti-altimedial-triangles triangle, or P-adjunct-anti-altimedial triangle for short(er).
The X(1)-adjunct anti-altimedial triangle is also the anticomplementary triangle of the inner Garcia triangle.
The P-altimedial and P-adjunct anti-altimedial triangles are homothetic for all finite P, and the center of homothety is P-of-orthocentroidal-triangle.
Let LA be the orthic axis of the A-altimedial triangle, and define LB, LC cyclically. Let A' = LB∩LC, and define B', C' cyclically. The triangle A'B'C' is here named the altimedial orthic axes triangle, or AOA triangle for short. The AOA triangle is inversely similar to the orthic triangle with center of inverse similitude X(15127). It is also homothetic to the 1st Hyacinth triangle at X(15120).
Let L'A be the orthic axis of the A-anti-altimedial triangle, and define L'B, L'C cyclically. Let A" = L'B∩L'C, and define B", C" cyclically. The triangle A"B"C" is here named the (anti-altimedial) orthic axes triangle, or AAOA triangle for short. The AAOA triangle is perspective to ABC at X(67), homothetic to the 1st Hyacinth triangle at X(15134), and to the AOA triangle at X(5094). The endo-homothetic center of the AOA and AAOA triangles is X(5219).
The homothetic center of these triangles is X(2).
The X(1)-altimedial triangle is the orthic triangle of the Fuhrmann triangle, and is perspective to ABC at X(79) and inversely similar to ABC, with similitude center X(1).

Perspeconics: X(15254)-X(15299)
This preamble and centers X(15254)-X(15299) were contributed by César Eliud Lozada, November 14, 2017.
Let ABC and A'B'C' be two perspective triangles such that neither is inscribed in the other. Let Ab = BC∩A'B', Ac = BC∩A'C', and likewise for Bc, Ba, Ca, and Cb. As ABC and A'B'C' are perspective, the pairs of lines {BC, B'C'}, {CA, C'A'} and {AB, A'B'} concur at three collinear points, and the lines AbAc, BcBa, CaCb join opposite vertices of an hexagon. By Pascal's theorem, the six points lie on a conic, here named the perspeconic of ABC and A'B'C'.

Always-perspective triangles and related centers: X(15428)-X(15445)
This preamble and centers X(15428)-X(15445) were contributed by César Eliud Lozada, December 2, 2017.
Centers X(1601)-X(1634) refer to perspectors of the tangential triangle and the circumcevian triangle of an arbitrary point P. This section deals with the perspectivities between a central triangle and a triangle depending on P.
Let P = u : v : w (trilinears) be a point not on the sidelines of ABC and let the reflections-of-P triangle be the triangle whose vertices are the reflections of P in the lines BC, CA, AB. The following pairs of triangle are perspective for all P:
The perspector Q(P) of these triangles is given by trilinears
Q(P) = b*c*(SA*u^2*(SB^2*v^2+SC^2*w^2)+a*u*v*w*(w*b+v*c)*(S^2-2*SB*SC)-SB*SC*a^2*v^2*w^2)+(S^4-2*SB*SC*(S^2+SA^2))*u^2*v*w : : /
Q(P) is the reflection in X(3) of the isogonal conjugate of the reflection in X(3) of the isogonal conjugate of P.
If P is at infinity, Q(P) is the isogonal conjugate of the antipode of the isogonal conjugate of P.
If P lies on the circumcircle and P' = circumcircle-antipode of P, then Q(SR(X(98), P)) = SR(X(98), P'), where SR(U,V) is the Simson-Rigby point of U and V. (See the preamble just before X2677 )

X(15451) is the center of circle {{X(4),X(15),X(16),X(186),X(3484)}} (or circle V(X(4)). This circle is orthogonal to the circumcircle and Brocard circle, and also passes through X(15412). (Randy Hutson, January 29, 2018)
X(15451) is the intersection of (isogonal conjugate of the polar conjugate of the orthic axis (i.e., line X(187)X(237))) and (polar conjugate of the isogonal conjugate of the orthic axis (i.e., line X(403)X(523))). (Randy Hutson, January 29, 2018)
For a given point P, the following trilinear polars concur:
trilinear polar of the isogonal conjugate of the isotomic conjugate of P;
trilinear polar of the polar conjugate of the isotomic conjugate of P;
trilinear polar of the isogonal conjugate of the polar conjugate of P;
trilinear polar of the isotomic conjugate of the polar conjugate of P.
The point of concurrence, Q, is the crossdifference of the isotomic conjugate of P and the polar conjugate of P, which is the barycentric product P*X(647). If P = X(5), the point of concurrence is X(15451). (Randy Hutson, January 29, 2018)

Another construction for points Ab, Ac, Bc, Ba, Ca, Cb on this conic: Let A'B'C' be the medial triangle. Let Ba', Ca' be the circumcircle intercepts of line B'C', and define Cb', Ab', Ac', Bc' cyclically. Then Ba is the {Ba',Ca'}-harmonic conjugate of B', Ca is the {Ba',Ca'}-harmonic conjugate of C', and cyclically for Cb, Ab, Ac, Bc. (Randy Hutson, January 29, 2018)

This preamble and centers X(15648)-X(15669) were contributed by César Eliud Lozada, December 28, 2017.
Let T1=A1B1C1 and T2=A2B2C2 be two perspective triangles, neither inscribed in the other.
Denote:
1) ab = A1B2, ac = A1C2, bc= B1C2, ba = B1A2, ca = C1A2, cb = C1B2
2) Ab = ab∩bc, Ac = ac∩cb, Bc = bc∩ca, Ba = ba∩ac, Ca = ca∩ab, Cb = cb∩ba
Then the six points Ab, Ac, Ba, Bc, Ca, Cb lie on a conic, here named the cross-perspeconic of T1 and T2.

POINTS ON THE EULER LINE, BY COMBOS: X(15670)-X(15723)
Certain points on the Euler line are easily represented as combos, as defined in the Introduction, in Part 1. If P and Q are points on the Euler line, then the points h P + k Q, where h and k are constants, comprise the thinline of P and Q, denoted by TL(P,Q). Points X(15670)-X(15680) are on TL(X(2),X(21)), and points X(15681)-X(15723), X(15759), X(15764), X(15765) are on TL(X(2), X(3)).
The Euler line contains infinitely many thinlines, all of which contain the point X(2)-X(3) at infinity. Otherwise, distinct thinlines meet in at most one point.
In general, if P and Q are points, then many combos h P + k Q are composites of the midpoint and reflection operations. Let m = midpoint and r = reflection. Then
P + Q = m(P,Q)
P - 2 Q = r(P,Q)
3 P + Q = m(P,m(P,Q))
3 P - Q = m(r(Q,P)),P)
3 P - 2 Q = r(r(P,Q)),P)
3 P - 4 Q = r(P,r(P,Q))
4 P - 5 Q = r(r(Q,P),r(P,Q))
5 P + 3 Q = m(m(m(P,Q),r(Q,P)),Q)
An open question is whether h*P+k*Q is such a composite for all choices h, k or integers (not both 0). Note that TL(P,Q) also contains points such as P + 21/2*Q which is not such a composite.
The appearance of (h,k,j) in the following lists (Groups 1 to 9) means that the point h*X(2) + k*X(3) = X(j), on TL(X(2),X(3)):

Given a triangle ABC and a point P, let c(P) be the circumconic having perspector P, and let A' be the center of the conic that passes through P and is tangent to c(P) at B and C. Define points B' and C' cyclically. The triangles ABC and A'B'C' are orthologic if and only P is on the sextic (passing through X(2), X(6)) having this barycentric equation:
Cyclic sum [ y z(17(b^2-c^2) x^4- ((15a^2+31b^2-19c^2) y-(15a^2-19b^2+31c ^2) z)x^3+ a^2(y+z)(y-z)^3) ]= 0.
If P is the centroid then the orthologic center of A'B'C' with respect to ABC is X(15692). The reciprocal orthologic center is X(4). If P is the symmedian then the orthologic center of ABC with respect to A'B'C' is X(18535). The reciprocal orthologic center is X(3). (Angel Montesdeoca, December 12, 2022)

Let Ae and Ai be the intersections of the perpendicular bisector of BC and the circle passing through X(5) centered at the midpoint of BC. Define Be, Bi, Ce, Ci cyclically (see K798). Let A'B'C' be the anticomplementary-of-anticomplementary triangle. Then X(15717) is the radical center of the circumcircles of A'AeAi, B'BeBi, C'CeCi. (Randy Hutson, January 29, 2018)

Euler lines and Brocard axis concurrences: X(15766)-X(15799)
This preamble and centers X(15766)-X(15799) were contributed by César Eliud Lozada, January 02, 2018.
Let r be the Euler line of ΔABC and P a variable point. Let ra, rb, rc be the Euler lines of the triangulation of P, here defined as ordered triple (ΔPBC, ΔPCA and ΔPAB) of triangles. Then, if P is on the Neuberg cubic, the four lines r, ra, rb, rc concur.
Under the same conditions, the Brocard axes of ΔABC, ΔPBC, ΔPCA and ΔPAB concur.
The appearance of (i,j) in the following list means that for P=X(i) on the Neuberg cubic, the three Euler lines concur in X(j):
(1, 21), (3, 3), (4, 5), (13, 2), (14, 2), (15, 11146), (16, 11145), (74, 3), (399, 15766), (484, 15767), (616, 15768), (617, 15769), (1138, 30), (1157, 15770), (1263, 5), (1276, 15771), (1277, 15772), (1337, 3130), (1338, 3129), (2132, 15773), (2133, 15774), (3065, 21), (3440, 3129), (3441, 3130), (3464, 15775), (3465, 15776), (3466, 15777), (3479, 3479), (3480, 15778), (3481, 15779), (3482, 15780), (3483, 15777), (3484, 15781)

Tangential perspeconics: X(15808)-X(15886)
This preamble and centers X(15808)-X(15886) were contributed by César Eliud Lozada, January 8, 2018.
If A'B'C' and A"B"C" are two perspective triangles, neither inscribed in the other, then the six lines A'B", A'C", B'C", B'A", C'A" and C'B" are tangent to a unique conic, here named the tangential perspeconic of A'B'C' and A"B"C".
Suppose the first triangle is the reference triangle ABC and the second is a central triangle A'B'C', perspective to ABC at X = x : y : z (barycentrics). Then XA'/XA = λa, XB'/XB = λb and XC'/XC = λc, where λa = λ(a,b,c), λb = λ(b,c,a), λc = λ(c,a,b) and λ(a,b,c) is a degree-0 homogeneous function of a,b,c. In this case, the center Q of the tangential perspeconic of ABC and A'B'C' is:

Suppose that DEF and D'E'F' are perspective triangles, and let U be the perspector. Let D'' = E'F∩EF', and define E'' and F'' cyclically. Then D''E''F'' is perspective to DEF; let V be the perspector. Also, D''E''F'' is perspective to D'E'F'; let W be the perspector. The points U, V, W are collinear. (Thanh Oai Dao, January 11, 2018).
Example: Relative to a reference triangle ABC, let DEF be the incentral triangle and D'E'F' the Feurbach triangle. Then U = X(11), V = X(12), and W = X(15888). (Peter Moses, January 11, 2018)

This preamble and centers X(15915)-X(15928) were contributed by César Eliud Lozada, January 20, 2018.
The gamma triangle Γ(T) of a triangle T is defined as the triangle having vertices the isogonal conjugates of the orthopoints of the sidelines of T. (TCCT, 6-46, pp. 178-179). From this definition, it is clear that every member of a set of homothetic triangles has the same gamma-triangle.
It is proved in the given reference that if T is not a degenerated triangle then T and Γ(T) are similar. Their center of similitude will be named here as the gamma-center of similitude of T.

Points associated with the Garcia reflection triangle: X(15995)-X(15999)
The Garcia reflection triangle is introduced here as follows. Let A' be the excenter of a triangle ABC, and define B' and C' cyclically. Let A'' be the midpoint of segment BC, and define B'' and C'' cyclically. Let A* be the reflection of A' in A'', and define B* and C* cyclically. Emmanuel Jose Garcia conjectured that the triangle A*B*C*, here named the Garcia reflection triangle, is perspective to the outer-Garcia triangle. César Lozada proved (January 28, 2018) that the conjecture is true. He found barycentric coordinates:
A* = a : c - a : b - a
B* = c - b : b : a - b
C* = b - c : a - c : c
Lozada also noted that A*B*C* is perspective to other triangles. The appearance of (T,n) in the following list means that A*B*C* is perspector to T and that the perspector is X(n). An asterisk ( * ) means that the triangles are homothetic:
(anticomplementary, 8), (Atik, 8), (2nd circumperp, 21), (Conway, 21), (2nd Conway, 8), (3rd Conway, 1), (excenters-midpoints*, 2), (excenters-reflections, 3680), (excentral, 9), (2nd extouch, 9), (Fuhrmann, 8), (outer-Garcia, 8), (hexyl, 1), (Honsberger, 2346), (Hutson intouch, 1), (outer-Hutson, 7707), (incircle-circles, 1), (intangents, 1), (intouch, 1), (inverse-in-incircle, 7), (medial, 9), (6th mixtilinear, 1), (2nd Pamfilos-Zhou, 7133), (Pelletier, 3309), (2nd Schiffler*, 11), (1st Sharygin, 21), (inner-Soddy, 15995), (outer-Soddy, 15996), (tangential-midarc, 15997), (Yff central, 7707)
Lozada established that A*B*C* is orthologic to other triangles. The appearance of (T,m,n) in the following list means that X(m) = A*B*C*-to-T orthologic center and X(n) = T-to-A*B*C* orthologic center:
(ABC, 1, 8), (ABC-X3 reflections, 1, 944), (anti-Aquila, 1, 10), (anti-Ara, 1, 12135), (5th anti-Brocard, 1, 12195), (anti-Euler, 1, 12245), (anti-Mandart-incircle, 1, 3913), (anticomplementary, 1, 145), (Aquila, 1, 3632), (Ara, 1, 12410), (Ascella, 8, 12437), (Atik, 8, 12448), (1st Auriga, 1, 12454), (2nd Auriga, 1, 12455), (5th Brocard, 1, 12495), (1st circumperp, 8, 12513), (2nd circumperp, 8, 3913), (inner-Conway, 8, 3621), (Conway, 8, 12536), (2nd Conway, 8, 12541), (3rd Conway, 8, 12546), (Euler, 1, 355), (3rd Euler, 8, 12607), (4th Euler, 8, 3813), (excenters-midpoints, 3680, 12640), (excenters-reflections, 8, 3680), (excentral, 8, 2136), (extouch, 4, 8), (2nd extouch, 8, 12625), (Fuhrmann, 1320, 10912), (inner-Garcia, 80, 3632), (outer-Garcia, 1, 1), (Gossard, 1, 12626), (inner-Grebe, 1, 12627), (outer-Grebe, 1, 12628), (hexyl, 8, 12629), (Honsberger, 8, 12630), (Hutson extouch, 15998, 12632), (inner-Hutson, 8, 12633), (Hutson intouch, 8, 8), (outer-Hutson, 8, 12634), (incircle-circles, 8, 3244), (intouch, 8, 145), (inverse-in-incircle, 8, 5836), (Johnson, 1, 1482), (inner-Johnson, 1, 10912), (outer-Johnson, 1, 12635), (1st Johnson-Yff, 1, 2099), (2nd Johnson-Yff, 1, 2098), (Lucas homothetic, 1, 12636), (Lucas(-1) homothetic, 1, 12637), (Mandart-incircle, 1, 10950), (medial, 1, 1), (5th mixtilinear, 1, 145), (6th mixtilinear, 8, 11519), (2nd Pamfilos-Zhou, 8, 12638), (1st Schiffler, 6597, 6598), (2nd Schiffler, 3680, 12641), (1st Sharygin, 8, 12642), (tangential-midarc, 8, 12643), (2nd tangential-midarc, 8, 12644), (3rd tri-squares-central, 1, 13911), (4th tri-squares-central, 1, 13973), (X3-ABC reflections, 1, 12645), (Yff central, 8, 12646), (inner-Yff, 1, 12647), (outer-Yff, 1, 10573), (inner-Yff tangents, 1, 12648), (outer-Yff tangents, 1, 12649)
Lozada also proved that A*B*C* is parallelogic to other triangles. The appearance of (T,m,n) in the following list means that X(m) = A*B*C*-to-T parallelogic center and X(n) = T-to-A*B*C* parellelogic center: (1st Parry, 1, 13250), (2nd Parry, 1, 13251), (2nd Sharygin, 8, 13252)
The Garcia reflection triangle A*B*C* has the same area as the reference triangle ABC, and the points A, B, C, A*, B*, C* lie on the Feuerbach hyperbola. (Emmanuel Garcia, March 3, 2018)
A* is the orthocenter of BCX(1), and cyclically for B*, C*. The Garcia reflection triangle is also the Gemini triangle 8, and the reflection of the 2nd Schiffler triangle in X(11). (Randy Hutson, June 7, 2019)
